Researchers from Nordic and German institutions are developing DNA-based testing using polygenic risk scores to predict antidepressant medication effectiveness for depression and anxiety patients. This pharmacogenomic approach analyzes genetic variations associated with mental health conditions and medication response to potentially reduce treatment trial-and-error.
Researchers have developed a highly sensitive and selective fluorescent probe for imaging serotonin, which is relevant to understanding depression diagnosis, treatment, and drug development. This tool enables better visualization of serotonin-related biological processes in depression research.
Research demonstrates that sleeping nine or more hours nightly correlates with reduced cognitive performance, with this effect amplified in individuals with depression. The finding aligns with established understanding of hypersomnia as a depressive symptom with measurable cognitive consequences.
Finasteride (hair-loss medication) has documented associations with depression and suicidal ideation in post-marketing data. The article argues regulators have inadequately addressed these psychiatric risks despite evidence.
